With seating for 70,000, U.S. Bank Stadium sits in downtown Minneapolis and is home to the Minnesota Vikings. Danny’s Construction Company erected the steel roof which sits over 300 feet tall and consists of 13,000 tons of structural steel, a 1,000-foot-long ridge truss, and queens post trusses that span over 350 feet. Danny’s Construction Company was brought on early to provide design assistance and contribute to the 3D modeling process to help with the overall jobsite coordination and scheduling. Our in-house team of engineers provided a complete erection plan including shoring, access planning, temporary stability and crane pick plans.
Using Navisworks Tekla, the erection plan, shoring tower placement, assembly areas and crane locations were identified on a 4D model. That model was used throughout the project for everyday jobsite coordination. The erection schedule for this project was extremely aggressive and although we were working on a zero-float path throughout the project, we were able to complete the roof two weeks early. In addition, Danny’s Construction Company exceeded the project workforce and business goals while employing over 100 workers.
We were pleased to be working with general contractor, Mortenson Construction, and steel fabricator, LeJeune Steel Company. Our construction team, comprised of Local 512 Iron Workers and Local 49 Operators, worked in cooperation with our engineering team and safety support to meet all daily expectations and complete another successful project.
Danny’s Construction Company was involved with more than just the erection of the steel roof; we were also contracted for the following scopes of work:
- Erection and installation of the 5 largest operable doors in the country.
- Installation of over 9 miles of aluminum and glass handrail both inside and outside of the stadium.
- Assistance in the installation of the ETFE roofing – installing both ETFE pillows and components on each purlin prior to erection to accelerate ETFE installation in the air.
- Erection of over 300 precast panels in the snow catchment. The snow gutter is as much as 50 feet deep, over 300 feet in the air, and at a slope of more than 38 degrees.
